GODFRIED WEILAND, OF DAYTON, OHIO.

Letters Patent No. 101,196, dated March4 22, 1870; an-tedated December 14, 1869.

The Schedule referred to in these Letters Patent and making part of the same.

frame of the machine, and operated by a hand-lever.

My invention consists of two ball-and-socket joints, with an intermediate hinge, so constructed and arranged as to hinge the rake-head to the main frame of the machine without the use `of screw-bolts, or bolts andkeys, 85o., as hereinafter set forth.

In the drawings- Figure I is a sectional elevation of a horse-rake l provided with my improvements.

Figure II is a plan view.

Figure III, a front elevation thereof. V Figure IV is a detached view of one of the guidestaudards.

Figure V is a-detached view of one of the cast boxes for fastening the rake-teeth.

Figure VI is a detached view of the locking-lever.

Like letters designate like parts in each of the iignres.

A A are the wheels.

B, the axle.

C, the thills, rigidly attached to the axle, and connected by cross-beams D D.

central brace, E, runs from the forward crossbeam 1),-underneath the-beam D', to the axle B.

These parts form the main frame of the machine.

'Ihe rake-head, located above the axle, consists of two parallel beams, F F', connected together, and arranged one behind the other. It is hinged to the axle B by two ball-and-socket joints, H H, the ball portions h of which are fastened tothe axle, while the socketed portions 71, are attached to the under side of the rake-head.

Between these two joints is arranged a hinge, I, forming an additional connection and means for securing the rake-head to the axle B.

The lower portion j of this hinge is fastened to the axle B, and is cast with a stud or pin, j,.which rits into aueye provided in the upper portion i2 ofthe hinge attached to the rake-head. K

The parts being connected together, as shown, the hinge Iprevents the vertical displacement of the ball-` and-socket joints, while the construction ofthe latter is such as to prevent lateral derangement.

In order to fasten the rake-teeth G to the rakehead, I bend the upper end or head of said teeth at right angles to the straight part thereof. A cast box or socket, N, having a groove, n, receiving the bent head of' the tooth, and a top piece, n', overlapping said part of the tooth, is provided for each tooth, and fastened to the face of the front beam F of the rake-head. The head of the tooth is held firmly between this box and the beam F, the groove nin the box retaining the same against lateral movement, while the projection An' prevents any vertical displacement of the same.

A guide-standard, O, attached to the beam F of the rake-head, is provided for -each tooth, the latter passing through a vertical slot, o, in the standard, which retains the tooth against lateral movement,but allows of a vertical play of the same.

The length of the slot o1 is adj usted by a stop, o?, filling the former to a certain extent, and thereby limiting the vertical movement.

A coiled spring, P, inclosing the body of the standard, expands between the head p ofthe same and the tooth G, and renders the latter seliladjusting to the irregularities of the ground when raking.

The improved mode of hinging the rake-head dispenses with the use of screw-bolts, belts, and keys, Src.,

which parts are frequently lost, and thereby occasion i greater or lesser inconvenience, while the hinging is such as to allow the rake-head all necessary freedom of movement.

K is a bent hand-lever pivoted to the frame, the short arm of which is connected, by a rod, L, to an arm, M, cast with and projecting from the upper portion of the hinge L.

The locking-lever It -is pivotcd to the cross-piece D' of the main flame in such a manner that the bent upper portion r of the same will preponderate, and press the lower portion r1 of same against the lower arm 7e of hand-lever K, which is firmly held in a notch,

. r2, with which the lower portion r1 of lever R is provided.

A pull applied to the upper portion r of locking-lever R will release the lever K, and permit it to be swung backward, to oscillate the rake-head and raise the teeth from the ground.

By letting go the hand-lever K, the gravity of the parts will cause them to assume their former position.

What I claim as my invention is- The ball-and-socket joints H H and intermediate hinge I, when arranged with the axle B and the rake-- head, substantially as and for the purpose set forth.
